I have beautiful white Embdens, 2 ganders & 4 geese. (Our original goose, Gertrude, is my avatar picture now) The ladies are a layin' like crazy right now! I don't want to incubate any of the eggs this year, and cannot find anyone else who wants them. I have been cracking them to eat, but many of them have an odd color to the yolk. Some have the beautiful golden yellow yolk, but many instead are a dull greenish-tannish-mustard-y yellow. The whites seem to be a bit cloudy in these too. They all are collected daily from the nests the girls make around the yard. The odd-colored ones don't smell bad, but I find it off-putting, I don't want to eat them. What could be the cause of this? Would it affect their fertility if someone wants to incubate them? Are they really all right to eat? I've been giving them away with the chicken and duck eggs that I sell, as something interesting to see, perhaps eat, or to use for crafts. I don't want someone to have an unpleasant surprise when they open them.
